2-Methyl-5,6-dinitrobenzimidazolium chloride

In the title compound, C8H7N4O4+·Cl , the cation possesses twofold symmetry, with the twofold axis bisecting the 2-methyl-5,6-dinitrobenzimidazolium cation. The methyl H atoms are disordered about this twofold axis and were assigned equal half-occupancies. The chloride anion also lies on a twofold axis. In the crystal, N—H...Cl and C—H...O hydrogen bonds link the ions to form a three-dimensional network.
